Programming the logger

A flowmeter with a digital pulse output is connected to a channel of the logger. The
flowmeter transmits one pulse per 16 litres.
Input type:
Unit:

The checkbox Fast-pulse-mode must be activated if a sensor is used with a
pulse rate >50 Hz (ie, more than 50 pulses per second). Otherwise, it may result in
inaccurate measurements.
Select whether the flow shall be measured per hour or per second.
If you want to compare your results to the values of a water meter, you have the chance
to enter the water meters’ counter reading into the respective field prior to the
measurement.
A flowmeter is connected to channel 3. In addition to the flow rate itself, the flow
direction shall be determined. For this purpose, a sensor which indicates the flow
direction by means of voltage values is connected to another channel of the logger.
Input type:
Sign slave for other channel
First of all, it has to be specified which direction is indicated by the 5 V value. A voltage
value of 0 V automatically indicates the opposite direction.
Furthermore, the channel (flow), the determined flow direction applies to, has to be
selected (in this case Channel 3).
